Ultra-low Carbon Steel vs. Pure Iron
Ultra-low carbon hlau:
Ultra-low carbon steel, raws li lub npe qhia, yog hom hlau uas muaj cov ntsiab lus tsis tshua muaj carbon. Feem ntau, ultra-low carbon steel muaj cov ntsiab lus carbon tsawg dua 0.03% (los yog qis dua, nyob ntawm qib tshwj xeeb). Cov ntsiab lus qis carbon no ua rau ntau yam khoom muaj txiaj ntsig, xws li txhim kho weldability, siab dua ductility, thiab txhim kho corrosion kuj.
Ultra-tsawg carbon steel yog dav siv nyob rau hauv daim ntawv thov uas cov khoom no tseem ceeb heev, xws li automotive Cheebtsam, siab hlab ntsha, thiab piping systems. Cov ntsiab lus carbon tsawg txo qhov kev pheej hmoo ntawm vuam tawg thiab txhim kho tag nrho cov khoom siv kho tshuab ntawm cov khoom.
Hlau ntshiab:
Cov hlau ntshiab, ntawm qhov tod tes, hais txog cov hlau uas tau ua kom zoo kom tshem tawm cov impurities feem ntau, nrog rau cov pa roj carbon. Hauv nws daim ntawv purest, hlau muaj tsawg dua 0.002% carbon thiab feem ntau hu ua electrolytic hlau los yog high-purity hlau. Cov hlau ntshiab muaj qhov tshwj xeeb lub cev thiab cov khoom sib nqus uas ua rau nws tsim nyog rau cov ntawv thov tshwj xeeb, xws li electromagnetic cores, transformers, thiab lwm yam khoom siv hluav taws xob.
Ib qho tseem ceeb sib txawv ntawm ultra-low carbon steel thiab ntshiab hlau yog muaj cov ntsiab lus alloying. Ultra-tsawg carbon steel tej zaum yuav muaj me me ntawm alloying ntsiab xws li manganese, silicon, thiab nickel los txhim kho nws cov khoom siv kho tshuab. Cov hlau ntshiab, txawm li cas los xij, feem ntau tsis pub dawb los ntawm cov alloying cov ntsiab lus, tso cai rau nws nthuav tawm nws cov khoom sib nqus thiab hluav taws xob.
Kev sib piv:
Cov ntsiab lus carbon: Ultra-low carbon steel muaj cov ntsiab lus carbon uas feem ntau siab dua cov hlau ntshiab, txawm hais tias ob qho tib si muaj cov pa roj carbon tsawg.
Alloying Elements: Ultra-low carbon steel tej zaum yuav muaj cov ntsiab lus alloying los txhim kho nws cov khoom siv kho tshuab, thaum cov hlau ntshiab feem ntau tsis muaj cov ntsiab lus no.
Daim ntawv thov: Ultra-low carbon steel yog dav siv nyob rau hauv cov txheej txheem thiab txhua yam kev siv vim nws ua ke ntawm lub zog, ductility, thiab weldability. Cov hlau ntshiab feem ntau yog siv rau hauv kev siv hluav taws xob thiab sib nqus vim nws cov khoom tshwj xeeb.
Nyob rau hauv cov ntsiab lus, thaum ultra-low carbon steel thiab ntshiab hlau sib xws nyob rau hauv cov nqe lus ntawm lawv cov ntsiab lus carbon tsawg, lawv txawv heev nyob rau hauv cov nqe lus ntawm lawv cov alloying ntsiab thiab npaj daim ntawv thov.
